Dynamaic Paint Not Spreading Blender 2.79b
No answers posted to my question.  To fix the problem, I started from scratch.  Then I added more points where the brush touched the canvas (letters), in order to get the paint to spread to the letters.  I did remove all previously baked images, but after I was done, I did see a physics file I did not remove.

While it got the job done, I'm sure this is not the best way to correct the problem nor does it explain why the paint would not spread to all the letters
